EL MAR® T GEO

VERY LOW-ASH NATURAL GAS ENGINE OIL

Phillips 66® El Mar T GEO is a high-quality, very low-ash, dispersant-detergent gas engine oil designed for use in naturally aspirated and moderately turbocharged, low-to medium-speed 2-stroke cycle and 4-stroke cycle natural gas engines.

EL MAR® T GEO

Features & Benefits

  • Field-proven performance in providing excellent engine cleanliness
  • Good dispersancy protects against sludge and varnish formation
  • Low-ash formulation helps minimize port deposits
  • Excellent resistance to oxidation and nitration
  • Protects against scuffing and wear
  • Protects against rust and corrosion
  • Does not contain any bright stock, which can cause harmful carbon deposits

Applications

  • Low-to medium-speed, 2-stroke cycle gas engines where port plugging is a concern
  • Low-to medium-speed, naturally aspirated 4-stroke cycle gas engines
  • Medium-speed, 4-stroke cycle gas engines operating under moderate loads
